Definitions

  • some manufacturing methods for a coil-and-rod electrode include a step in which the altered stable operation shape of the electrode is obtained in advance, for example by melting the tip of the electrode and some of the coil to form a fused area at the front face of the electrode. A method to do this is by laser-melting the electrode tip.
